This device comprises a hollow support ( 13 ) delimiting, in the vicinity of a distal end ( 19 ), a transverse retention opening ( 23 A). It comprises an endoprosthesis ( 11 ) which can be deployed between a state retracted against the support ( 13 ) and an expanded state. The device comprises a filamentary connection ( 33 A) forming a clamping ring ( 43 ) surrounding the endoprosthesis ( 11 ) and forming a loop ( 45 ) engaged in the support ( 13 ) through the retention opening ( 23 A). The device comprises a retention rod ( 31 A) mounted to be movable in the support ( 13 ). The retention rod ( 31 A) comprises a hook ( 35 ) for retaining the loop ( 45 ). The displacement of the retention rod ( 31 A) from a release position to a retention position brings about the tightening of the clamping ring ( 43 ). Application to the release of endoprostheses in a blood circulation canal.
